Description

Technical Field

[0001] This utility model relates to the field of vehicle parts manufacturing technology, and in particular to a composite extrusion molding tooling for precision forging of vehicle gears. Background Technology

[0002] Vehicle gears are core mechanical components in vehicle transmission systems, primarily used to transmit power, change speed and direction, and are key elements to ensure the normal operation of vehicles. Precision forged vehicle gears are gear parts manufactured through precision forging processes. Their core lies in "near-net-shape forming" technology, meaning that the parts can be used after forming with only a small amount of machining or no machining at all. Precision forged gears are widely used in core components of automotive transmission systems.

[0003] In the existing technology, when forging vehicle gears, the workpiece is usually formed by pressing the upper die against the inner wall of the lower die. However, the workpiece will stick to the inner wall of the lower die due to the huge pressure of the upper die, which makes it difficult to remove the workpiece from the lower die. This makes it difficult to unload the formed workpiece and affects the processing progress. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite extrusion molding tool for precision forging of vehicle gears.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite extrusion molding fixture for precision forging of vehicle gears, including a processing table, a fixed frame fixedly connected to one side of the upper surface of the processing table, a hydraulic cylinder fixedly installed on the upper surface of the fixed frame, an upper die fixedly connected to the output end of the hydraulic cylinder, a lower die fixedly connected to the middle of the upper surface of the processing table, and a material discharge component provided at the bottom of the lower die;

[0006] The discharge assembly includes two through slots, which are formed at the bottom of the inner wall of the lower mold. A T-slot is formed on one side of the processing table, and a fixed shell is fixedly connected to both sides of the processing table.

[0007] As a further description of the above technical solution:

[0008] A first stepper motor is fixedly mounted on the lower surface of one of the fixed housings, and a drive stud is fixedly connected to the output end of the first stepper motor. The drive stud is rotatably connected inside the other fixed housing.

[0009] As a further description of the above technical solution:

[0010] The drive stud is externally threaded with a connecting rod, the connecting rod has a first threaded hole inside, one end of the connecting rod is fixedly connected to a U-shaped frame, and a second stepper motor is fixedly installed on one side of the upper surface of the processing table.

[0011] As a further description of the above technical solution:

[0012] The output end of the second stepper motor is fixedly connected to a screw, and the screw is externally threaded to an L-shaped frame. The L-shaped frame has a second threaded hole inside, and a limit groove is formed inside the upper surface of the processing table. The L-shaped frame is slidably connected inside the limit groove, and a mounting shell is fixedly connected to one end of the L-shaped frame.

[0013] As a further description of the above technical solution:

[0014] A stepper motor is fixedly mounted on one side of the mounting housing. A bidirectional stud is fixedly connected to the output end of the stepper motor. The bidirectional stud is rotatably connected inside the mounting housing. Two clamping brackets are threaded to the outside of the bidirectional stud. The two clamping brackets are slidably connected inside the mounting housing.

[0015] As a further description of the above technical solution:

[0016] A cooling component is provided on one side of the processing table. The cooling component includes a bidirectional air outlet shell, which is fixedly connected to the inside of one side of the processing table.

[0017] As a further description of the above technical solution:

[0018] A mounting frame is connected through one side of the bidirectional air outlet shell, a fan is fixedly installed inside the mounting frame, a dustproof plate is fixedly connected to one side of the mounting frame, and an air guide block is fixedly connected to the inner wall of the bidirectional air outlet shell.

[0019] This utility model has the following beneficial effects:

[0020] 1. With the setting of the discharge assembly, the U-shaped frame driven by the connecting rod moves upward, which facilitates the upward movement of the workpiece that has been extruded and formed inside the lower die. Under the pushing action, it helps the workpiece to separate from the inner wall of the lower die. When it moves to the top of the lower die, it is easy to remove the workpiece from the lower die. Furthermore, the two clamping frames that are close to each other can clamp the workpiece after it has been removed from the lower die. With the movement of the L-shaped frame, the workpiece can be easily moved away from the top of the lower die, which facilitates the timely discharge of the workpiece and reduces the phenomenon of delay in work progress.

[0021] 2. With the cooling component in this utility model, the workpiece can be easily moved to the cooling component through the discharge component. Under the action of the bidirectional air outlet shell blowing air on the workpiece in both the upper and lower directions, the formed workpiece can be cooled down quickly. Under the action of the air guide block, the air force delivered to the inside of the bidirectional air outlet shell through the mounting frame can be guided and conveyed. The air force is cut by the sharp corner of the air guide block, so that it is evenly delivered into the upper and lower directions of the bidirectional air outlet shell. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] As attached Figure 1-8 As shown, one embodiment of this utility model is provided: a composite extrusion molding tooling for precision forging of vehicle gears, including a processing table 1, a fixed frame 2 fixedly connected to one side of the upper surface of the processing table 1, a hydraulic cylinder 3 fixedly installed on the upper surface of the fixed frame 2, an upper die 4 fixedly connected to the output end of the hydraulic cylinder 3, a lower die 5 fixedly connected to the middle of the upper surface of the processing table 1, and a material discharge component provided at the bottom of the lower die 5.

[0034] The discharge assembly includes two through slots 6 to facilitate the passage of the U-shaped frame 13. When ejection is not required, one end of the U-shaped frame 13 is set inside the through slot 6, with its upper surface flush with the bottom of the inner wall of the lower mold 5. The two through slots 6 are opened at the bottom of the inner wall of the lower mold 5. A T-slot 7 is opened on one side of the processing table 1 to facilitate the passage of the U-shaped frame 13 and the connecting rod 11. Fixed shells 8 are fixedly connected to both sides of the processing table 1.

[0035] As attached Figure 5 As shown, a first stepper motor 9 is fixedly installed on the lower surface of one of the fixed housings 8. The output end of the first stepper motor 9 is fixedly connected to a drive stud 10, which facilitates the drive stud 10 to rotate. The drive stud 10 is rotatably connected inside the other fixed housing 8, so that the drive stud 10 can rotate stably.

[0036] As attached Figure 6 As shown, the external thread of the drive stud 10 is connected to a connecting rod 11. The connecting rod 11 has a first threaded hole 12 inside, which matches the thread of the drive stud 10. One end of the connecting rod 11 is fixedly connected to a U-shaped frame 13, which facilitates pushing the workpiece upward after passing through the through groove 6.

[0037] As attached Figure 1 As shown, a second stepper motor 14 is fixedly installed on one side of the upper surface of the processing table 1. A screw 15 is fixedly connected to the output end of the second stepper motor 14. An L-shaped bracket 17 is connected to the external thread of the screw 15. When the screw 15 rotates, it is convenient to drive the L-shaped bracket 17 to move through the second threaded hole 18.

[0038] As attached Figure 7As shown, the L-shaped frame 17 has a second threaded hole 18 inside, which matches the thread of the screw 15. The upper surface of the processing table 1 has a limit groove 16 inside, which facilitates the limiting of the L-shaped frame 17. The L-shaped frame 17 is slidably connected inside the limit groove 16. One end of the L-shaped frame 17 is fixedly connected to a mounting shell 19 for mounting a bidirectional stud 21. A stepper motor 20 is fixedly mounted on one side of the mounting shell 19. The output end of the stepper motor 20 is fixedly connected to the bidirectional stud 21 with opposite external threads. The bidirectional stud 21 is rotatably connected inside the mounting shell 19. The external threads of the bidirectional stud 21 are connected to two clamping brackets 22. The two clamping brackets 22 are slidably connected inside the mounting shell 19 to clamp the workpiece and drive its movement.

[0039] As attached Figure 8 As shown, a cooling component is provided on one side of the processing table 1. The cooling component includes a bidirectional air outlet shell 23, which is fixedly connected to the inside of one side of the processing table 1. The bidirectional air outlet shell 23 facilitates airflow from two directions. A mounting frame 24 is connected through one side of the bidirectional air outlet shell 23. A fan 26 is fixedly installed inside the mounting frame 24. A dust baffle 25 is fixedly connected to one side of the mounting frame 24 to reduce external dust from drifting into the fan 26. An air guide block 27 is fixedly connected to the inner wall of the bidirectional air outlet shell 23 to guide the airflow.

[0040] Working principle: After the upper mold 4 is pressed and formed by the output end of the hydraulic cylinder 3, when the upper mold 4 and the lower mold 5 are separated, the second stepper motor 14 is first turned on by the controller, so that the output end of the second stepper motor 14 drives the screw 15 to rotate. Under the action of the second threaded hole 18, the screw 15 drives the L-shaped frame 17 to slide in the limiting groove 16, which indirectly drives the two clamping frames 22 to move to both sides of the lower mold 5. Then the first stepper motor 9 is turned on, and its output end drives the drive stud 10 to rotate, so that the drive stud 10 drives the connecting rod 11 to move down first. When the connecting rod 11 drives the U-shaped frame 13 to move down, it will open the gap with the through groove 6 inside the lower mold 5, thereby releasing the U-shaped frame 13 from the bottom of the formed workpiece.

[0041] Then, the output end of the first stepper motor 9 is driven to rotate in the opposite direction. When the output end drives the drive stud 10 to rotate in the opposite direction, it will drive the U-shaped frame 13 to move upward through the connecting rod 11. This causes the U-shaped frame 13 to push the workpiece inside the lower mold 5 upward, pushing the workpiece out of the lower mold 5 and moving the workpiece above the lower mold 5. Then, the stepper motor 20 is turned on, and the rotation of its output end drives the bidirectional stud 21 to rotate. Under the action of the threads on both sides of the bidirectional stud 21 in opposite directions, the clamping frames 22 on both sides move closer to each other, making it easier to clamp the workpiece.

[0042] Then, the reverse rotation function of the second stepper motor 14 is turned on, and its output end drives the screw 15 to rotate in the opposite direction. When the screw 15 drives the L-shaped frame 17 to move, it will indirectly drive the clamped workpiece to move away from the top of the lower mold 5.

[0043] When the L-shaped frame 17 indirectly moves the workpiece to the middle of the bidirectional air outlet shell 23, the fan 26 is turned on, so that the air force of the fan 26 is delivered to the interior of the bidirectional air outlet shell 23 through the mounting frame 24. Under the guidance of the air guide block 27, the air force is easily divided into two directions and delivered to the two directions of the bidirectional air outlet shell 23 for air outlet, thereby cooling the workpiece.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
